It was. My phone said 80, it felt like 90 in the sunny side......but that's probably because it was the first time most of us were in the sun since the Penn State game last year. It did seem "brutally hot."
Perhaps they could have made a gameday call to close off the sunny side and have everyone on the other side but then people would complain about having to walk all the way to the other side to get to their seats since most people come from the Great Hall side.
Its got to be said if being too hot and sunny for an April 15 scrimmage is a complaint item, then that is something a lot of places would like to complain about.
